<u>Answer:</u>
<u>Positive factors of 30 are:</u> 1, 2, 3, 5, 6, 10, 15, 30
<u>Step-by-step explanation:</u>
We are asked to list the positive factors of the number 30.
Factors are the whole numbers which when multiplied together produce another number. So positive factors only include the whole numbers that are greater than 0.
Positive factors of 30 include the following whole numbers:

Answer:
substitute that value for x in the polynomial and see if it evaluates to zero
Step-by-step explanation:
A "zero" of a polynomial is a value of the polynomial's variable that make the expression become zero when it is evaluated. As an almost trivial example, consider the polynomial x-3. The value x = 3 is a zero because substituting that value for x makes the expression evaluate as zero.
3 -3 = 0
___
Evaluating polynomials can be done different ways. Straight substitution for the variable is one way. Using synthetic division by x-a (where "a" is the value of interest) is another way. This latter method is completely equivalent to rewriting the polynomial to Horner form for evaluation.
